Increase GPM in your Delavan

You can increase your total gpm in you Delavan's performance by not only wiring your 12VDC pump to a marine grade battery but to also run a wire to your vehicle battery. You will maximize the performace by turning on your vehicle while running your Delavan. The 5850 and Fatboy need the 30 charging amps for full power! (According to Bill at Delavan)
 
I guess I'm good then. That's exactly how I have mine set up. It's also good because when your running from one job to the next it continually keeps your Marine Battery charged. I've never once had to charge the battery. Great advice. Thanks Lori. :thumbup2:
 
Good point, I notice the same with my electric reels too, I only reel up my 200 feet of 1/2" hose with the Kohler running. The fat boy is hard wired to that battery as well, never used the fat boy other than to transfer water out of the chem tanks

I tried that once without any luck. I ran a hot and ground wire off the battery that plugged in to my trailer light plug. The power went to the acc. lead (trailer brake charger). The black went to ground.
I read about doing this online and thought this was charging my battery while the truck was running. It wasnt.

Well one day right when I was finishing up a roof, the battery died. So I had the battery charged and bought a charger. $45.00, then found the same one at Kmart for half the price.:bash:

I've got JUST a hot wire with a fuse link off the battery of my truck that runs under the truck to a welders connecton (male end). The female end is on my trailer and runs directly to the marine battery. The ground wire (Neg) on is connected to a bolt on my trailer. This way I'm not messing with my truck lights or tailer lights or any other connections. So far so good. I've never had a problem with wiring it this way.

What gauge hot wire Larry?

I believe it is 12 gauge. ( May be 10 though) It's best to use the same size wire for the negative as you use for the possitive. I also have a fuse link between the battery and the pump just for added safety.

Thanks Larry.
 
If you use even a 10 gauge wire for a run all the way to a the vehicle battery without any isolation and the battery at your Delavan fails completely it will attempt to pull the full 26 amps through the 20' of 10ga. You will need a fuse because that will melt your 10ga wire. It Sounds like Larry has it covered. A marine battery with a 60AH rating will allow you in theory to pull 30 amps for 2 hours straight. Many newer trucks have a circuit in the trailer harness that allows for charging on the go but at a low rate. I believe they are isolated to prevent running the vehicle's battery down. A second battery in parallel would be a good option for longer continued use. Running the 10ga to the battery is a great idea as long as nothing goes wrong with the Delavan's main battery.
 
why not use a power inverter with a batt charger. or a dual batt. switch for your truck just in case it drains the batt out in the truck. you can have 2 batts. charging full time and hit the switch at any time to turn the other off.
 
It's much easier and cheaper to install a battery isolater. It allows charging to the #2 battery but won't allow the #2 battery to drain the main. No switching needed.
 
Thanks for posting this info Lori, I did not know this stuff.

I was always thinking that you can just run it off a large marine battery and when the battery is dead then charge it.

I have the charging circuit on the trailer 7 wire plug to keep the Breakaway battery charged, maybe I need to run a wire off that to the marine battery to keep it charged while driving and when it is totally dead then plug it in to charge overnite?

I have a marine battery that is for the Hannay electric hose reel that I was going to also use for the delavan for chemical spraying, not sure if I should do that now or if I should get a separate battery for that?

I only roll up that hose when done so maybe a few times a day depending on the work load but the Delavan would be used for maybe 10-20 minutes here and there throughout the day to spray chems as needed, maybe I can use the same marine battery for both?

Thanks.
